This next step involves installing the raw drywall patch. Measure the thickness of the existing wall or ceiling you're repairing and make sure to use the same thickness of wallboard for the patch. In 90% of the cases it will be 1/2" thick.
- Measure the opening of the area to receive the patch.
- Cut a piece of drywall to fit the opening.
- Place the patch in the opening with the light colored paper side out
- Fasten to the blocking supports with the drywall screws in each corner and approximately 6" apart along the lengths of the opening.
